Elevator Tied Up or Tied Down?

[WAVEGURU]

When tying down a glider, should the stick be tied back, with the elevator in the up position, or should the stick be tied forward, with the elevator in the down position?

If the tail of the glider is tied down then it's not going to make the slightest difference which way you do it. The only consideration is that the controls not be able to flap around. If you can do that by tying the stick forward then go for it, but it's usually much easier to tie it backwards. And don't forget, you're immobilising the ailerons just as much as the elevator.

If the elevator has drain holes, you want those down so internal condensation can drain out.

This is most certainly not true if the glider has mylar seals on the elevator. In this case the elevator must be secured so the mylar seals are not deflected or they will either take a set and not contact the surface or, in the extreme, may separate. Same is true when the glider bits are stored in the trailer. The control surfaces should be restrained in the neutral position if mylar seals are used.
